Description
Sound-level meter SL328 is a compact measuring instrument for determining ambient sound levels across a measuring range of 32 to 130 dB. It supports noise assessment, workplace checks, and general acoustic monitoring in laboratories, technical rooms, and related environments where sound pressure levels must be recorded. The handheld format and low mass of 0,230 kg make the device convenient for spot measurements and portable surveys without bulky equipment. Supplied as one unit, it belongs among measuring instruments for miscellaneous parameters used alongside other laboratory metrology tools. This sound-level meter from manufacturer Dostmann is intended for users who need a clearly specified dB range for routine sound-level readings rather than a multi-parameter environmental station. Typical applications include verifying background noise, checking equipment-related sound output, and documenting acoustic conditions during experiments or facility inspections. Choose the SL328 when you require a dedicated sound-level meter with a 32–130 dB measuring range for practical laboratory and technical measurement tasks.
This article is part of pH meters, in pH & electrochemistry.

Questions about Sound-level meter SL328, measuring range 32 - 130 dB, 1 unit(s)
What is this article?
Sound-level meter SL328, measuring range 32 - 130 dB, 1 unit(s) is the article on this page. Luminix Health distributes Dostmann for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
Which category should I open next?
